You could also have Googled. This one even has the same title as your question - http://bytes.com/topic/php/answers/488284-php-http-https-how-can-one-tell

A:
$protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https'?'https':'http';
$protocol = isset($_SERVER["https"]) ? 'https' : 'http';
These should both work

A:
If the request was sent with HTTPS you will have a extra parameter in the $_SERVER superglobal - $_SERVER['HTTPS']. You can check if it is set or not
if( isset($_SERVER['HTTPS'] ) ) {

The problem with this approach is that it doesn't always work, as the `$_SERVER` documentation says: "The entries in this array are created by the web server. There is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here."

If the server is properly configured, is shouldn't be a problem. Better to try this approach first and resort to hacks if it fails

A:
$_SERVER['HTTPS']
This will contain a 'non-empty' value if the request was sent through HTTPS

A:
You should be able to do this by checking the value of $_SERVER['HTTPS'] (it should only be set when using https).

This can get more complicated depending on where PHP sits in your environment, since your question is quite broad. This may depend on whether there's a load-balancer and how it's configured. Here are are a few related questions:
